I believe it would be a wiser choice to go to the dealer and try it for yourself first? Because fit and comfort is a big deciding factor in my opinion, even more than the sound itself, because if it doesn't fit, you won't wear them anyway. Then you could decide between what's left?
Personally, i don't know the XC, the Focal Clear could need some EQ for better bass and less aggressive mid area and the arya as well, because i found the treble too annoying compared to the 1000V2 and the heddphone sounds better to my ears compared to the 1000V2, but may need a bit of eq as well around bass and mid section.
Arya and 1000V2 don't slam or punch hard, the heddphone is better there and audeze in general seems to punch and slam harder and got less distortion as well. Focal Clear, as far as i know, is known for clipping problems, which means if you eq or listen very loud, you should buy your unit at the dealer's places and test it out first before purchase
